The forged steel gate valve features an outside screw and yoke (OS&Y), and rising stem. Bolted or welded bonnet joint. Solid wedge gate, integral backseat. full or standard port.

BODY - The body is forged steel and designed to the basic dimensional requirements of the applicable specifications such as API 602 and ASME B16.34. The body is available in both the full or standard port design.

BONNET - The bonnet is forged steel, has an integral backseat, and incorporates the stuffing box.

BONNET JOINT - bolted bonnet or pressure seal and seal welded type.

SEAT RING - The seat rings are pressed into the valve body and wedged into place, forming a seal with the body. The seating surfaces are ground and lapped.

WEDGE - The wedge is a solid design, forged, and the surfaces are ground and lapped.

STEM - The stem is forged steel and it contains an integral back seat shoulder, which mates with the integral back seat of the bonnet. The stem is made to meet the basic size requirements of the relevant standards, like API 602.

Other Features

1. GASKET. The bolted bonnet joint design valve uses a contained, controlled compression, spiral wound type gasket.

2. GLAND AND FLANGE. The gland, gland flange assembly utilizes a separate, two piece design. This self aligning design allows the flange to be unevenly tightened while the gland maintains it’s parallel alignment with the stem and stuffing box.

3. GLAND BOLTS AND NUTS. The steel/stainless steel gland bolt and nut assembly is a stud, double nut arrangement. This design allows complete removal from the valve when service is required. The use of industry standard thread full length studs and nuts also allows easy replacement should these items be lost or in need of replacement.

4. YOKE SLEEVE. The yoke sleeve is of forged stainless steel material having a high melting point and is resistant to wear and corrosion.

5. HANDWHEEL. The handwheel is forged carbon steel of an open spoke design. This robust construction along with appropriate sizing allows for ease of operation.
